I would be looking at second-hand bags from the likes of Lowe Alpine, Berghaus, The North Face, Deuter, Early Karrimor (Before they were bought out by Sports Direct), then your looking at military packs from various armies around the world that may be similar to this one:

Osprey make really good packs but they still go for decent money second-hand & are likely to be out of reach. A lot of the hiking style rucksacks may have side-pockets but their capacity will be nothing like that of the more military type bags.

It's a tough ask but you may find something but I would personally avoid going down the rugged looking but suspiciously cheap road due to stitching & lack of quality issues.

You could spend £150 on lets say 3 rucksacks that may only last you 3-5 years but you could just as easily spend £100 on one that could last you a lifetime.

I would go for an ex-military SUPERGRADE or GRADE 1 rucksack myself but the chances of you getting one in plain green or black are fairly limited.

Good luck & if I see or here of anything that might tick all the boxes I will let you know !

Thanks mate,
Yes, I did mean to say 'Used' also and somewhere external to put my axe would be good too.
Quite like that Austrian one and suppose I could add side pouches but that's more cost. Budget is kind of limited shall we say!

I am using in that size the Decathlon X-Access Hunting Rucksack 50 Litres, which is very light and in my opinion strong enough, if you use it carefully, but I recommend to use it with lightweight equipment. I would not load more than 10 kg, because for me than it becomes uncomfortable.
